Question. Do you always lose your mucus plug before labor starts? With my first I had every sign that labor was coming. I couldn't have missed it lol mucus plug was lost two days before I had him, I felt low, and the day I had him I woke up from a nap and all of my weight shifted to the front. I know they are all different, but I'm hoping this one is just as obvious that he's coming lol
